Your camera keeps stopping mid recording, and the card is usually why. Most people buy on capacity alone.

A big card can still be slow, and video needs steady write speed, not just space. Check the V rating on the card, V30 or higher for four K video, and make sure your camera supports it.

Buy from a proper seller, because fake cards are common online. And format the card in the camera, not on your computer.

Do that, keep a spare card in your bag, and you avoid dropped frames, corrupted clips and lost footage. Cheap cards cost little, but a lost shoot costs a lot.

Spec for spec, speed rating beats size.
